About this image

Just north of the hematite deposit in Meridiani Planum, the remnants of a formerly extensive layer of material remain as isolated knobs and buttes. Note the transition from north to south in the size and frequency of these features, a reflection of the decreasing elevation along this trend. Small dune forms occupy the floor of the crater at the top of the image.
